2filesystem.lua - Platform-independent filesystem operations
3
4A comprehensive, standalone filesystem module for Lua with no external dependencies.
5This module provides a consistent interface for file and directory operations across
6all platforms that support Lua.
7
8Usage:
9 local fs = require("lib.tools.filesystem")
10 local content = fs.read_file("path/to/file.txt")
11 fs.write_file("path/to/output.txt", "Hello, world!")
12
13Design principles:
14- Complete independence: No imports from other modules
15- Generic interface: All functions usable in any Lua project
16- Minimal dependencies: Only relies on Lua standard library
17- Platform neutral: Works identically on all platforms

2filesystem.lua - Platform-independent filesystem operations
3
4A comprehensive, standalone filesystem module for Lua with no external dependencies.
5This module provides a consistent interface for file and directory operations across
6all platforms that support Lua.
7
8Usage:
9 local fs = require("lib.tools.filesystem")
10 local content = fs.read_file("path/to/file.txt")
11 fs.write_file("path/to/output.txt", "Hello, world!")
12
13Design principles:
14- Complete independence: No imports from other modules
15- Generic interface: All functions usable in any Lua project
16- Minimal dependencies: Only relies on Lua standard library
17- Platform neutral: Works identically on all platforms
